NavPix is the proprietary name applied by Navman
to its technology that combines an image with geographical data.
The "NavPix" name is used for both the software and the geo-referenced image that results from that software.
image using the integrated digital camera on the N Series ("N" for NavPix), iCN 720 or iCN 750 portable Navman GPS navigation devices.
The Navman's GPS (Global Positioning System
) receiver determines the latitude and longitude of where that image was taken. That information is then written into the image's Exif (Exchangeable image file format
) meta data by the NavPix software. The NavPix, therefore, effectively provides a Georeference
of the location where the image was taken, which is not necessarily the same georeference as the object being "NavPix-ed".
The NavPix image can then be used to define a destination or point of interest
on compatible Navman devices.
.
The NavPix Library also enables people to upload non-NavPix images (including other formats such as GIF
) and convert them to NavPix images by using entering either the latitude and longitude they want to associate with the image or by entering the address and using the Library's software to generate the latitude and longitude values based on a Postal code
look-up.
Unlike some geo-referencing applications, the NavPix Library writes the georeference values to the image itself via the Exif meta data.

To georeference something means to define its existence in physical space. That is, establishing its location in terms of map projections or coordinate systems. The term is used both when establishing the relation between raster or vector images and coordinates, and when determining the spatial...

Point of interest
A point of interest, or POI, is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Space Needle, or a point on Mars representing the location of the mountain, Olympus Mons.The term is widely used in...
